Being leveled by depression or anxiety, unable to engage in daily activities, is no joke. But before seeking an antidepressant or other mood-altering medications, you may want to start by having your thyroid levels checked.
THYROID DISORDERS AND MENTAL HEALTH
Thyroid disorders are one of the leading causes of undiagnosed mental health issues. An overactive thyroid can make you feel sped-up and anxious, in a state of perpetual over-caffeination. An underactive thyroid typically means
lower brain activity, which can lead to depression,
brain fog, or irritability. In more than 430,000 scientific articles,
depression has been linked with lowered thyroid levels.
“Patients with hypothyroidism and those with depression can present with similar general symptoms,” according to the
American Thyroid Association.
Because many mood disorders may have a fundamental root cause in thyroid disorders, it’s wise to have blood work done to see if you may be suffering from an underactive thyroid, in the form of hypothyroidism or Hashimoto’s disease; an overactive thyroid, with a disease called Grave’s disease; or any number of other related conditions.
A gland shaped like a bowtie wrapped at the front of your lower neck, the thyroid is a key regulator of the body’s metabolic processes. It also oversees the production of many neurotransmitters, such as dopamine, serotonin and GABA, which explains its paramount role in brain health.
COMMON SYMPTOMS OF THYROID AND MENTAL HEALTH ISSUES
For more than 200 years, the medical profession has identified the connection between optimal thyroid function and mental health.
An Anglo-Welsh physician named Caleb Parry all the way back in 1825 noted “nervous affectations” in people suffering from thyroid dysfunction. More than a century later, in 1969, depression was identified as a potential early sign of thyroid disease. It is also linked to
schizophrenia,
borderline personality disorder,
bipolar disease,
ADD/ADHD, and other mental health problems.
Before seeing your doctor, look for additional symptoms that could indicate there is more than meets the eye in your mental health struggles. They may include weight loss or gain, hair loss, fluctuations in your body temperature—feeling generally too hot or too cold—changes to your menstrual cycle, or persistent troubles with diarrhea or constipation.
Other
symptoms to look for include:
- Sluggishness
- Racing thoughts
- Memory problems
- Trouble sleeping or unrestful sleep
- Cramps or pain in your muscles or joints
- Brittle nails
- Extra dry skin
- Yellowing skin
- Symptoms of psychosis
- Episodes of mania
- Attentional problems or difficulty concentrating
- Swelling in the front of your neck, which could indicate a swollen thyroid
Some of these symptoms on their own, such as difficulty sleeping and concentrating, can be primary symptoms of depression. However, the existence of one or several at the same time also could indicate your thyroid is involved.
Blood work can reveal low or high levels of the three main thyroid hormones, including thyroid-stimulating hormone, or TSH; thyroxine, or T4; and triiodothyronine, called T3. If so, treating your thyroid first to re-establish optimal hormonal levels may resolve, or at least lessen, psychiatric symptoms.
KNOW YOUR THYROID BLOOD TESTS—AND YOUR DOCTORS
While standard thinking holds that healthy levels of TSH, or thyroid-stimulating hormone, should range between .5 and 5 in blood work results,
not every medical professional agrees. A TSH test reveals just how hard the thyroid gland is working to keep a person’s metabolism working. The higher the test score, the harder the gland is pumping out hormones to jolt you into gear. Generally speaking, lower TSH test results indicate the metabolism is in balance, working well enough on its own, without this assist.
Some doctors, often those with a greater focus on lifestyle or integrative health, believe optimal results should always be below 2 or 2.5. The lower reading ideally indicates the gland is not over-stressed.
So be aware that some more traditional doctors may not prescribe thyroid medication when a test shows a TSH between 2 and 5. They may only do so when the test comes in above 5, or even higher. To treat subclinical hypothyroidism may require a visit to a
functional or integrative doctor.
WHAT FACTORS WRECK THYROID HEALTH AND CONTRIBUTE TO MENTAL ILLNESS?
A wide variety of factors, acting alone or in combination, can conspire to undermine thyroid health, including dietary factors and exposure to
environmental toxins.
One of them is a rapid loss of a large, or even moderate, amount of weight. When you lose weight rapidly,
your thyroid slows, producing lower levels of TSH. This can throw off the delicate balance that the body must maintain in producing different thyroid hormones. In particular, rapid weight loss can result in a diminished ability to convert T4, also known as a “prohormone,” into the more active T3.
Dietary factors such as gluten sensitivity and celiac disease, both of which involve reactions to the gluten in wheat, can trigger thyroid disorders. For people with either, eating gluten can create leaky gut symptoms and release an antibody that can attack the thyroid. Given that celiac disease is often accompanied by thyroid disorder,
one clinical study suggests gluten-free diets can help people struggling with thyroid health. Other studies have found that a failure to adhere to a gluten-free diet, for people with these risk factors, can contribute to a host of debilitating diseases such as osteoporosis, anemia, and increased
risk of mortality.
Zinc deficiency is another
risk factor, a particularly pervasive one given the
depletion of zinc in many plants. Along with copper and selenium, zinc is required for the production of thyroid hormones. On the other side of the coin, thyroid hormones are necessary for the body to absorb zinc, which means hypothyroidism itself can lead to a zinc deficiency. When it comes to hair loss caused by hypothyroidism, often hormone supplementation won’t be sufficient without proper zinc supplementation.
Lastly, women with hypothyroidism who take supplemental estrogen for their health
may need to increase the amount of thyroxine or T4 they take in order not to prevent a drop in their thyroid function.
SUPPLEMENTS FOR THYROID BALANCE AND HELP FOR MENTAL HEALTH
In addition to seeking a functional doctor, a wide variety of
natural supplements can boost your thyroid health. These include ashwagandha; zinc (which supports healthy hair); selenium; the herb rosemary; l-tyrosine; potassium; chromium; and vitamins A, B2, B3, B6, C, and D. Consult with your doctor to ensure your supplements support and do not conflict with your medications.
If psychiatric symptoms, such as anxiety, depression, attention issues, psychosis, or mania persist after regulating your thyroid levels, it’s time to seek help from a mental health professional.
